Improved spring bed-bottom



waited 'States @met @Wm Letters Patent No. 103,646, dated May 31, 1870.

IMPRovnD SPRING BED-BOTTOM.

''he Schedule referred to in these Letters Patent and making part of thesame` ence being had to the accompanying drawing making a part hereof,in which- Fignre l is'a sectional side elevation of a` detachedV potionf a bed-bottom embodying my improvements, an

Figure 2 a plan of the same.

My invention relates to that class of spring bedbottoms in which narrowslats are connected, at head and foot, with the inclined arms of coilsprings, and consists in a device whereby each slat, it' bent orsprungdownward, may be inverted; in the combination of certain elementsto form sections, and in the combination of the sections so formed. Eachsection consists of atop and bottom slat connected at each end by aleather, spring, and block. v

lhe construction and arrangement of the several sections being the sameat both ends, only one end thereof is shown in the accompanying drawing,in which i The parts marked a a are the bottom slats.

b b' are blocks or elevations, arranged as shown, and made fast to suchslats.

At each end ofthe several sections, and connecting the same, isa rod, c,passing through the blocks b'b,

and allowing snch sections to move laterally thereon.

d d' are set-screws, hearing on rod c, whereby the several sections areconined at any given point or distance apart.

c e are double-coil springs, the legs whereof enter vthe blocks b b',and the united arms whereof, projecting forward and upward, form eyes j'f', through which eyes pass the leathers g g', whereby the top slats hh' are connected with the springs.

Instead of attaching-the leathers g g' to the surface of slats h h', Imake a horizontal slot in the ends of such slats, and confine therein,by nails or otherwise, theleat-hers g g', as in fig. 1.

Through vertical holes in slats h 71. I pass movable pins it', andprovide both ends of such pins with heads, knobs, or projections. l

The leathers g g', after passing through eyes ff', hook or fasten ontopins t t beneath slats h h. "lo invert such slats, detach them from thesprings, press on the projecting portions of pins t i till the voppositeends thereof project from the opposite sides of slats h h', turn theslats over and attach them to `the springs as before, and this devicemay be used with a single or double-coil spring, and the pins 't 'i' maybe made permanent and ixed in slats h h', without altering the nature orprinciple of the separate sections, considered as sections.

I am aware that spring bed-bottoms have heretofore been constructed insections,and' I do not claim such a device, broadly, but confine myselfto the sections, and the combination thereof', herein specified.

. Claim.

I claim as my inventiont The combination, by means of rods c andscrewsd, of two 0r more sections, severally composed of slats a h, blocks 11,springs e, leathers g, and pins i, all con'- strnct-ed, ar ranged, andoperating in the manner and for the purpose specified.
